Half Life of Charge on metal ball.
Let a metal ball of Radius \(r\) is placed in infinite homogeneous conducting medium having dielectric constant \(k\) , resistivity \(\rho\) . Let at time t=0 , Q charge is given to ball , then find the half Life of the charge present on sphere.
Inspired from Raghav's Note
It is simple version of that problem.
Yes Answer is independent of Size of ball...
